⚡ Compute Sharing (Salad-style)

Compute sharing rents your GPU VRAM to AI inference, rendering, and ML training workloads. Salad.io, Vast.ai, and Akash pay based on GPU model and market demand. Rates shown are Salad.io averages — Vast.ai can pay 20–35% more with port-forwarding configured.

Electricity cost per hour

watts ÷ 1000 × $/kWh

230W ÷ 1000 × $0.120/kWh

= $0.0276/hr

US residential average: ~$0.12/kWh. Check your electric bill for your exact rate.

EIA: U.S. residential electricity avg ~$0.12–0.16/kWh (2024)

Net earnings per hour

gross/hr − electricity/hr

$0.2500 − $0.0276

= $0.2224/hr

4

Daily → monthly earnings

net/hr × hours/day × 30.44 days/mo

$0.2224 × 8hr × 30.44

= $1.78/day · $54.16/mo

5

Payback period

GPU MSRP ÷ monthly net earnings

$699 ÷ $54.16/mo

= ~13 months

Only relevant if you bought the GPU for this purpose. Already-owned hardware earns pure profit.

Key insight

Mining income (when received) and compute sharing payments are both taxable as ordinary income. Track your earnings and set aside 25–35% for taxes if you have no W-2 withholding.
